Hi @nigelpoulton ,
I'm following thru your
Getting Started with Docker
course from pluralsight last updated 27 Oct 2020
I get this error when I try to build the image.
Seems like the Dockerfile has been removed?
Please advice how to fix this.
ls
on the command linefirst-container multi-container README.md swarm-stack
sudo docker image build -t <my_dockerhub_id>/gsd:1 --no-cache .
unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat <my_directory>/docker/demos/gsd/Dockerfile: no such file or directory
I'm running on Ubuntu 20.04.4 LTS
With docker version: Docker version 20.10.14, build a224086
Thanks!
While running 'docker image build -t /gsd:first-ctr .' command in git bash I am getting following error
$ docker image build -t <docker_id>/gsd:first-ctr .
